A murder investigation has been launched after a man was stabbed to death at a party at the home of the former world champion boxer Herbie Hide, police have said.

Officers were called to the private party in Bawburgh, Norwich, at 12.07am on Sunday, Norfolk constabulary said. The victim, in his 20s, was pronounced dead at the scene at 12.44am.

A police spokesman said: "Mr Hide and his family have relocated as police carry out investigations at the scene."

Police said there were about 100 people at the party. Detective Superintendent Julian Gregory, from the joint Norfolk and Suffolk major investigation team, said: "We are in the early stages of our investigation and working to establish the sequence of events which led to this man's death.

"We are also in the process of confirming the victim's identity and police family liaison officers have been assigned to work with next-of-kin.

"A large number of people are known to have been present at the property at the time and while we continue our efforts to identify and speak to all partygoers, I would urge anyone who left the scene before speaking to police to contact Norfolk constabulary as soon as possible."
